    • A multicenter study on Leigh syndrome: disease course and predictors of survival 

      Sofou, Kalliopi; De Coo, Irenaeus F. M.; Isohanni, Pirjo; Ostergaard, Elsebet; Naess, Karin; De Meirleir, Linda; Tzoulis, Charalampos; Uusimaa, Johanna; De Angst, Isabell B.; Lönnqvist, Tuula; Pihko, Helena; Mankinen, Katariina; Bindoff, Laurence; Tulinius, Már; Darin, Niklas (Peer reviewed; Journal article, 2014-04-15)
      Background: Leigh syndrome is a progressive neurodegenerative disorder, associated with primary or secondary dysfunction of the mitochondrial oxidative phosphorylation. Despite the fact that Leigh syndrome is the most ...
    • Phenotypic spectrum and clinical course of single large-scale mitochondrial DNA deletion disease in the paediatric population: a multicentre study 

      Björkman, Kristoffer; Vissing, John; Østergaard, Elsebet; Bindoff, Laurence Albert; de Coo, Irenaeus F M; Engvall, Martin; Hikmat, Omar; Isohanni, Pirjo; Kollberg, Gittan; Lindberg, Christopher; Majamaa, Kari; Naess, Karin; Uusimaa, Johanna; Tulinius, Mar; Darin, Niklas (Journal article; Peer reviewed, 2023)
      Background: Large-scale mitochondrial DNA deletions (LMD) are a common genetic cause of mitochondrial disease and give rise to a wide range of clinical features. Lack of longitudinal data means the natural history remains ...
    • Simplifying the clinical classification of polymerase gamma (POLG) disease based on age of onset; studies using a cohort of 155 cases 

      Hikmat, Omar; Naess, Karin; Engvall, Martin; Klingenberg, Claus; Rasmussen, Magnhild; Tallaksen, Chantal; Brodtkorb, Eylert; Østergaard, Elsebet; de Coo, Irenaeus F.M.; Pias-Peleteiro, Leticia; Isohanni, Pirjo; Uusimaa, Johanna; Darin, Niklas; Rahman, Shamima; Bindoff, Laurence (Journal article; Peer reviewed, 2020)
      Background Variants in POLG are one of the most common causes of inherited mitochondrial disease. Phenotypic classification of POLG disease has evolved haphazardly making it complicated and difficult to implement in ...
